Background
The main constituent materials of the secondary battery may include an active material, a binder, a conductive material, pores, and the like, and the structure of the active material among these main constituent materials is highly related to the efficiency of the battery. In particular, the active material may exhibit abrupt phase change of a crystal structure according to a change in volume due to repeated charge and discharge, which results in slow reaction, reduced output of the battery, and shortened life span.
In order to increase the capacity of secondary batteries including lithium ion batteries (Li-ion batteries) and the like, there are various methods of evaluating the structure of a main active material. Among conventional methods for analyzing active materials, raman spectroscopy is widely used because it can measure a local site and has advantages of an easy measurement method. These general evaluation methods evaluate an active material by turning on a battery that is charged and discharged at a specific voltage. However, there are problems in that it is difficult to directly measure due to stability problems and it is difficult to analyze the structure of the active material in real time.
Therefore, in order to improve the efficiency of the secondary battery, it is necessary to develop a device for analyzing the structure of the active material in real time.

In the following description of the present application, if it is determined that detailed description of related known technology may obscure the gist of the present application, the detailed description of related known technology will be omitted.
When a constituent element is referred to herein as being "interconnected" or "connected" with another constituent element, it should be understood that the constituent element may be directly interconnected or connected with the other constituent element or that other constituent elements may exist between the constituent element and the other constituent element.
Unless otherwise indicated, singular expressions include plural expressions.
As used herein, an expression such as "comprising," "including," or "having" means that there is a feature, value, step, operation, constituent element, component, or combination thereof described in the specification, but that these expressions do not exclude the possibility that other features, digital figures, steps, operations, constituent elements, components, or combinations thereof not mentioned in the specification are present or added.
Hereinafter, an apparatus for analyzing an active material according to an embodiment of the present application will be described in more detail.
As shown in fig. 1 and 2, an apparatus for analyzing an active material according to the present application may include: a lower plate 10, the electrode 2 being placed on the lower plate 10; an upper plate 20, the upper plate 20 being coupled to the lower plate 10, and the electrode 2 being interposed between the upper plate 20 and the lower plate 10; a sealing member 30, the sealing member 30 being located at a joint portion of the upper plate 20 and the lower plate 10; and a coupling member 40, the coupling member 40 for coupling the upper plate 20 and the lower plate 10.
The space between the upper plate 20 and the lower plate 10 may be filled with an electrolyte, and the upper plate 20 may include an opening 50, a light source may be irradiated to the electrode 2 through the opening 50, and the opening 50 may be covered with glass.
According to an embodiment, raman spectroscopy analysis may be performed through the opening 50 of the upper plate 20, i.e. the part made of glass. The opening 50 (a portion made of glass) may be formed in the shape of a transparent window at a portion of the center of the upper plate 20, and the position and shape of the opening 50 may be appropriately changed. For example, the opening 50 may be formed at a position opposite to the electrode 2 between the upper plate 20 and the lower plate 10.
The apparatus for analyzing an active material according to the present application may accommodate the electrode 2 in a space formed by coupling the upper plate 20 and the lower plate 10 face to face. That is, the upper plate 20 and the lower plate 10 may be coupled to each other with the electrode 2 interposed between the upper plate 20 and the lower plate 10.
Accordingly, the electrode 2 may be disposed in a sealed space formed by coupling the upper plate 20 and the lower plate 10. The connection portion of the upper plate 20 and the lower plate 10 may be provided with a sealing member 30 to minimize exposure to moisture. For example, the sealing member 30 may be an O-ring. The upper plate 20 and the lower plate 10 may be coupled to each other by a coupling member 40, and the coupling member 40 may be, for example, an adjusting screw. The electrolyte may be filled in the space between the upper plate 20 and the lower plate 10.
Due to the thickness of the sealing member, a space accommodating the electrode 2 may be obtained by a groove formed in the upper plate 20 or the lower plate 10 or a space formed between the upper plate 20 and the lower plate 10.
By using the device for analyzing an active material according to the present application, it is possible to analyze the change in the structure of the active material during the charge or discharge of the pouch-shaped polymer battery. According to an embodiment, the electrode 2 of the single cell type polymer battery is accommodated inside the device for analyzing an active material, and an electrolyte may be filled in the space between the upper plate 20 and the lower plate 10. The charge/discharge terminal 60, which can be electrically connected to the electrode 2, penetrates the upper plate 20 so that the lower end of the charge/discharge terminal 60 can be in contact with the electrode 2 or a tab extending from the electrode 2.
That is, the lower ends of the charge/discharge terminals 60 may protrude downward more than the upper plate 20, and the upper ends of the charge/discharge terminals 60 may protrude upward more than the upper plate 20. The charge/discharge terminals 60 may be a conductive material.
As shown in fig. 3, the electrode 2 includes a cathode and an anode, and the electrode 2 may be positioned between the upper plate 20 and the lower plate 10 in the stacking order of [ cathode ] - [ separation membrane ] - [ anode ]. The charge/discharge terminals 60 may be configured to be electrically connected to the cathode and the anode, respectively. For example, two charge/discharge terminals 60 may be provided.
In addition, the charge/discharge terminal 60 may be in contact with the tab of the electrode 2. The charge/discharge terminal 60 may be in direct contact with the electrode 2, but may be in contact with a tab electrically connected to the electrode 2 and protruding from the electrode 2.
A cable connected to a charging/discharging device (not shown) may be connected to an upper end of the charging/discharging terminal 60 in the upper plate 20, and thus a power source may be connected to the electrode 2. Since the charge/discharge terminals 60 are located on the upper plate 20, leakage of electrolyte can be minimized.
In other words, if the charge/discharge terminal 60 penetrates a structure arranged at a position lower than the liquid surface formed by the electrolyte and electrically connects the electrode 2 and the charge/discharge device, there is a risk that the electrolyte leaks through a hole through which the charge/discharge terminal 60 passes. However, according to the present application, the upper plate 20 through which the charge/discharge terminals 60 connected to the electrodes 2 pass is located at a position higher than the liquid surface formed of the electrolyte, so that leakage of the electrolyte is prevented.
According to an embodiment, the upper plate 20 and the lower plate 10 of the device for analyzing an active material may be formed of one or more materials selected from the group consisting of teflon, polyimide, and High Density Polyethylene (HDPE) having low electrical conductivity. Such a material can prevent the electric energy charged into the electrode 2 or the electric energy discharged from the electrode 2 from being applied to the upper plate 20 or the lower plate 10, and is chemically stable, so that it is unnecessary to construct an additional insulating sheet or the like.
According to an embodiment, the active material of the electrode 2 may include LTO (Li 14 Ti 15 O 12 )、NMC(Li[CoMnNi]O 2 )、LCO(LiCoO 2 )、NCM(Li[Ni,Co,Mn]O 2 )、NCA(Li[Ni,Co,Al]O- 2 )、LMO(LiMn 2 O 4 )、LFP(LiFePO 4 ) Or LCP (lithium cobalt phosphate).
In addition, the active material may include a carbon, silicon (Si) -based material, a nitride, a titanium (Ti) -based material, or a vanadium (V) -based material. Specifically, for example, the active material may include graphite, si/graphite, si-oxide, li, si-Sn, li x M y N 2 、Li 0.6 CoOO 0.4 Ti or V.
On the other hand, various modifications and changes may be made to the present application depending on the case of implementing the present application, without being limited to the above description. For example, raman spectrum analysis may be performed while charging and discharging by placing a pouch-type battery including the electrode 2 on the lower plate 10, coupling the upper plate 20 and the lower plate 10 without filling an electrolyte between the upper plate 20 and the lower plate 10, and connecting a charging/discharging device with the charging/discharging terminal 60 of the upper plate 20.
The coupling member 40 may be a bolt. The upper plate 20 may be provided with a through hole through which the coupling member 40 passes. The lower plate 10 may be provided with insertion holes or slots into which the coupling members 40 are inserted at positions corresponding to the through holes of the upper plate 20. The through holes, the insertion holes, or the insertion slots may be provided in plural. Threads are formed on an inner circumferential surface of the socket or the receptacle, and the socket or the receptacle may be coupled with the coupling member 40 by the threads. The screw thread is not formed on the inner circumferential surface of the through hole, so that the coupling member 40 can smoothly slide while passing through the through hole.
A plurality of through holes may be formed at positions adjacent to the edge of the upper plate 20. The insertion hole or the insertion groove may be formed at an edge of the lower plate 10 farther than the position where the sealing member 30 is disposed.
By using the device for analyzing an active material according to the present application, a change in the structure of an active material during charge or discharge can be analyzed in real time, and thus can be effectively used for development of a battery.
Hereinafter, examples of the present application will be described in detail to enable those skilled in the art to which the present application pertains to practice the present application. The application may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein.
Example 1
The upper and lower plates are made of teflon material. Specifically, the opening of the center of the upper plate is formed of circular glass for spectroscopic measurement, and a sealing member is arranged at the connection site between the upper plate and the lower plate.
Will be served as anodeLiCoO of (C) 2 And a polymer electrode composed of Si/graphite as a cathode is placed on the lower plate and coupled with the coupling member to laminate the lower plate and the upper plate.
Experimental example 1: structural change analysis of active materials
To analyze the structural change of the battery active material during charge and discharge, a current was applied to the polymer electrode of example 1. During the charge and discharge of the battery, raman spectra were obtained through an opening covered with glass on the upper plate using a raman spectrometer (almega XR manufactured by samer company (Thermo), laser: 532nm, objective lens: 50× (long working distance)) to check the structural change of the cathode active material in real time.
The charge and discharge curves are shown in fig. 4, and the raman spectrum results are shown in fig. 5.
As shown in FIG. 4, it was confirmed that the G band in the initial sample was indicated as 1575cm -1 And when the voltage is increased to 3.70V, a blue shift phenomenon of the G band occurs. The result is due to Li + Gradually intercalates between the graphene lamellar structures of graphite, whereby the spacing between the graphene lamellar becomes wider.
Furthermore, it can be seen that at a voltage of 3.75V, the G band of graphite is divided into 1570 (E 2g2(i) ) And 1595cm -1 (E 2g2(b) ) Two bands, meaning that li+ is a band that occurs when it gradually intercalates between adjacent graphene sheets of graphite.
In addition, E at a voltage of 3.84V or more 2g2(i) And E is 2g2(b) The strength of the tape gradually decreases and becomes 1588cm -1 Where a new band appears, indicating Li + Has been inserted into almost all graphene sheets.
As described above, with the device for analyzing an active material according to the present application, structural changes of the active material can be simply and easily confirmed in real time during charge and discharge of a battery.
Since specific constructions of the present application have been described in detail, it will be apparent to those skilled in the relevant art that the specific description is only of a preferred embodiment, and thus the scope of the application is not limited thereto. Accordingly, the true scope of the application should be defined by the following claims and their equivalents.
